Switched From Straight CPAP to AutoSet

[Buddhist Sage]

So, I have 2 sleep studies that show all I need is 9cmH2O on my back. How come my autoset goes way past that? Last night I was past 19cmH20? I feel great! But such high pressures are a concern for me. Last night was near perfect with an AHI of 0.1. I only had one Hypopnea towards the end of my sleep. But why so much pressure!?

Before I switched to the AutoSet, I had a feeling I needed more pressure since I always sleep on my stomach and not on my back. But I was never expecting so much! Does the Mirage Quattro Full Face Mask play a factor in this? My leaks are normally at 6, but there is one period where it went well past 24, for a breif moment.

Anyone with similar a similar experience?

Good God did I swallow alot of air last night, is there a fix for this?

You need to check what the maximum pressure your machine is set for. Sometimes a small leak can confuse it and it will keep ramping up to the maximum setting.

If you scrutinize your reports, you'll see for yourself why the pressure adjustments are doing what they're doing.
Without actually seeing the reports, we can only take wild guesses as to why.

If you have a prescribed pressure of 9 cm. and you thought you might need a little more, why didn't you just tweak it up a centimeter or two?
Using a range of pressures can be totally confusing for new users. They get a multitude of "problems" and don't know which is the chicken and which is the egg.

In order for us to provide you with any insight into the answer to that last question we need to see the following graphs:

The event table
The flow wave graph
The pressure graph
The snore graph
The flow limitation graph
The leak graph

The event table could be left off since the events are super imposed on the flow wave, but we need to see the all the other graphs on that list.

We DON'T need to see the AHI graph, the respriatory rate graph, the minute volume graph, the inspiratortory time graph, etc.

You know, I just realized I had my humidifier on with no water tub inside! I have the resmed s9 AutoSet with the humidifier. I'll provide graphs, but this water tub thing may be the root cause. Any opinions?

Wouldn't have anything to do with the pressure, but you were not getting any humidity, that's fer sure!

What are you trying to accomplish? Zero ahi is rare, not something you can get consistently. Don't drive yourself crazy trying to accomplish it. You can mess up your sleep.

If you ahi is consistently below 1, which it sounds like from previous posts, and your sleep is still messed up, then maybe it something else. Many people have more than one sleep issue.

I'm not trying to get 0.0AHI. I get very close 0.0AHI flawlessly. I'm just shocked my machine is almost maxing out at 20cmH20! This post is about pressure not perfection. I have other health problems as well, but they're not appropriate for this forum, all I will say is that severe insomnia has plagued me for 2 years and I couldn't get over it cause OSA was in the background undiagnosed. At night I take a low dose anti-depressant, 3mg of Melatonin Time Released, 2 Tablets of Cortisol Manager, and Some Ashwaghanda. Once I added an AutoSet to this I began to feel really good!

I just want to make sure I'm not doing something wrong to make my machine pump out so much pressure! But I feel great!! 2 nights in a row! I wonder what I will feel like a month from now if this keeps up!

Looks to me like flow limitations were a major cause of the pressure increases ....

[Pugsy]

You aren't spending an enormous amount of time up near 20 cm...just some of the time.
For some reason the machine thinks that there is something that it is sensing that warrants the increase in pressure.
It doesn't appear to be snores but it could be the flow limitations as they are a bit active around the time of the increase.

Also it is common to sometimes need more pressure when sleeping supine or during REM stage sleep..or heck maybe a combination of both.

When I was using the APAP my minimum was 10 cm and sometimes it never varied much above 11 or 12 and sometimes I would hit 20 at various times during the night. Since my OSA is documented much worse in REM sleep and since the pressure increases almost always coincided with the time frame where I was in REM sleep I have always assumed (and I my doctor agrees) that they were REM related. I have always been lucky in that the increases to 20 cm never bothered me. Never knew they even happened until I saw the report the next day. If the higher pressures are causing you to wake up then perhaps you might think about a little reduction in the maximum. The higher pressures may be more of a disturbance than whatever the machine is trying to fix.
Something to maybe talk over with your medical care team.

If you think it might be supine sleeping you might try staying on your back if you can. If it is REM related there isn't much you can do about REM.

I guess I don't understand why you changed your pressure when you already had great results. If you don't need that range of pressures, why use them? You were doing well before.

Yes number wise I was doing well before. I was under 5ahi but numbers aren't everything. I have a cortisol problem, it's too high and stubborn, so the small amount of events in the normal range were very stressful for me in my opinion. All I knew was that I was on straight cpap for 18 months and saw little improvement with memory mood anxiety and cognitive deficits. I tried adding pressure to my cpap machine, but I just didn't have the patience. A lightly used autoset popped up in my area and I bought it. These past 2 nights have been the best nights of sleep I've gotten this year! I think this quality of sleep is here to stay.
